Semitendinosus vs Gracilis Grafts With 1- vs 2-Tunnel Techniques for Coracoclavicular Ligament Reconstruction: A Biomechanical Study.

Background: Despite the evolution of acromioclavicular joint surgery to a more anatomic coracoclavicular (CC) ligament reconstruction, no definitive guidance regarding the number and position of bone tunnels in the clavicle, as well as the ideal graft choice, is established.

Purpose/hypothesis: The purpose of this study was to biomechanically compare the reconstruction of the CC ligament complex between gracilis- and semitendinosus-tendon grafts in 1- and 2-tunnel techniques. It was hypothesized that the gracilis tendon graft will provide comparable primary stability in both tunnel techniques while utilizing a smaller tunnel diameter.

Outcomes of Total Shoulder Arthroplasty With Posterior Capsular Plication.

Background: Glenoid loosening and instability are among the most common complications after anatomic total shoulder arthroplasty (TSA), resulting in poor function. Posterior instability is one contributing factor. The purpose of this study is to report the clinical and radiographic outcomes of a series of patients treated with posterior capsule plication for intraoperative posterior instability during TSA.

Incidence of and Risk Factors for Knee Collateral Ligament Injuries With Proximal Tibia Fractures: A Study of 32,441 Patients.

Proximal tibia fractures are associated with concurrent collateral ligament injuries. Failure to recognize these injuries may lead to chronic knee instability. The purpose of this study was to identify risk factors for concurrent collateral ligament injuries with proximal tibia fractures and their association with inpatient outcomes.

Incidence of and Risk Factors for Inpatient Stroke After Hip Fractures in the Elderly.

Although uncommon, stroke can be a catastrophic inpatient complication for patients with hip fractures. The current study determines the incidence of inpatient stroke after hip fractures in elderly patients, identifies risk factors associated with such strokes, and determines the association of stroke with short-term inpatient outcomes. A retrospective review of all patients aged 65 years or older with isolated hip fractures in the 2011 and 2012 National Trauma Data Bank was conducted.

Popliteal Artery Entrapment Syndrome: Bilateral Lower Extremity Involvement.

Popliteal artery entrapment syndrome is a condition in which compression of the popliteal neurovascular structures results in symptoms of lower extremity claudication by way of a constricting anatomic structure or a hypertrophied surrounding musculature. This diagnosis is often missed or misdiagnosed because popliteal artery entrapment syndrome has a presentation similar to that of exertional compartment syndrome. Popliteal artery entrapment syndrome may result in persistent disability or unnecessary morbidity or prevent athletes' return to sport.

Bilateral atypical femur fractures without bisphosphonate exposure.

Atypical femur fractures have common radiographic features that set them apart from more typical higher-energy subtrochanteric femur fractures. They are noncomminuted, transverse fractures with medial spiking of the femoral cortex and increased lateral cortical thickness. These fractures have been associated in the literature with the use of bisphosphonate medications.

Leiomyoma of the Foot and Ankle: A Case Series.

Unlabelled: Leiomyoma is a benign soft-tissue tumor that can arise in any soft tissue; however, in the extremities, it is usually a subcutaneous mass. Masses in the foot and ankle in general are rare, and few reports in the literature describe leiomyoma in this region of the body. We present a series of 8 cases of leiomyoma of the foot and ankle, 4 of which are subclassified as angioleiomyomas.
